'''CoolBooter''' is a tool for dual booting jailbroken 32-bit iOS devices with another copy of iOS via winocm's [[ios-kexec-utils]]. It supports hosts running iOS 7.0 or higher and can boot versions ranging from 5.0 to 8.4.1. Hosts on lower versions can install the [[#CoolBooterCLI|CLI version]] instead.
  +
  +
== Usage notes ==
  +
  +
* During setup, the user can choose to jailbreak the secondary operating system and/or activate verbose boot. iOS 8.x will automatically be jailbroken, as there will be issues if it is not.<ref>[https://twitter.com/Thmitt/status/941474872261214208 @Thmitt: there were some issues with 8.x if it wasn’t jailbroken]</ref>
  +
  +
* Hosts running iOS 9.0 or higher experienced issues with data protection, meaning that apps such as YouTube, WhatsApp and Mail would not work on the secondary OS. Experimental protected volume support was added later to work around these issues.
  +
  +
* Like regular installations of iOS, dual booted systems must be activated. [[A6]] devices that have ever been on iOS 10 and then downgraded have failed activation since July, 2017, first randomly, then consistently. To activate the dual booted partition on these devices, activation records can be copied to <code>/var/root/Library/Lockdown</code> from the host OS. Another option is to delete <code>/Applications/Setup.app</code>, also done from the host OS.
  +
  +
* The secondary OS will kernel panic during boot on A6 devices if the Lightning cable is plugged in, or has been since the device was booted into the host OS. To fix the issue, unplug the cable and reboot before launching CoolBooter.
  +
  +
* The secondary OS uses the same lock screen code as the host OS
  +
  +
* CoolBooter uses a [[kloader]] version that depends on [[tfp0]] and version 1.2.4 (APP) / 0.8.4 (CLI) and these versions are thus incompatible with the [[h3lix]] jailbreak for iOS 10.x. The problems can be worked around by replacing the multi_kloader binary with one compiled to use [[hgsp4]] instead of [[tfp0]]. Way Out 1.6.1 already uses the new binary and can be used to boot the secondary OS installed by CoolBooter.

CoolBooter is a tool for dual booting jailbroken 32-bit iOS devices with another copy of iOS via winocm's ios-kexec-utils. It supports hosts running iOS 7.0 or higher and can boot versions ranging from 5.0 to 8.4.1. Hosts on lower versions can install the CLI version instead.

Usage notes

  • During setup, the user can choose to jailbreak the secondary operating system and/or activate verbose boot. iOS 8.x will automatically be jailbroken, as there will be issues if it is not.[1]
  • Hosts running iOS 9.0 or higher experienced issues with data protection, meaning that apps such as YouTube, WhatsApp and Mail would not work on the secondary OS. Experimental protected volume support was added later to work around these issues.
  • Like regular installations of iOS, dual booted systems must be activated. A6 devices that have ever been on iOS 10 and then downgraded have failed activation since July, 2017, first randomly, then consistently. To activate the dual booted partition on these devices, activation records can be copied to /var/root/Library/Lockdown from the host OS. Another option is to delete /Applications/Setup.app, also done from the host OS.
  • The secondary OS will kernel panic during boot on A6 devices if the Lightning cable is plugged in, or has been since the device was booted into the host OS. To fix the issue, unplug the cable and reboot before launching CoolBooter.
  • The secondary OS uses the same lock screen code as the host OS
  • CoolBooter uses a kloader version that depends on tfp0 and version 1.2.4 (APP) / 0.8.4 (CLI) and these versions are thus incompatible with the h3lix jailbreak for iOS 10.x. The problems can be worked around by replacing the multi_kloader binary with one compiled to use hgsp4 instead of tfp0.
